Vertical tab-bar in landscape orientaion

Hi, Thanks to both of you. it is working fine but there is one issue. initially in MainTabbarView i have set tab-bar docked bottom. in controller based on orientations i have set tab-bar docked positions, those conditions i have given in below controller code. tab-bar and its items are coming fine during portrait orientation, in landscape orientation tab-bar is coming at right it is nice but tab-bar item are coming horizontal and also not able to see the icons of the items(See in below attached image within red box). i need to show these tab bar items in vertical order in landscape orientation. below i have given view code, controller code, styles and images. Tell me how to achieve this one.

Can you provide a demo? I understand if you have some privacy issues, but it would help (even if you could send it in a private message).

I have had that problem when I first started playing with the CSS to get it working, but it was a while ago and I can't remember how I got around it. In the meantime, I will look at my code and take away properties to see if I can get it to the point of how yours looks.
